Title: Dimming type sensor
Inventor: MORITA SHUNICHI
IPC: G01N21/59
Filed: 1987-09-03
Abstract: PURPOSE:To quickly detect even a slowly spreading fire, by inhibiting correction of a reference value for fire decision in case of considerable reduction from a normal value of the output of a light reception part. CONSTITUTION:When the output of a light reception part 13 is reduced and the absolute value of the change value first exceeds a threshold for negative change value decision in a ROM 4, a fire decision reference value storage means RAM 2 stores the output of the light reception part at this time as the reference value for first decision. A dimming rate calculating means calculates the dimming rate of the output of the light reception part to the reference value for fire decision at each time of sampling, and the reference value for fire decision is not updated as long as the absolute value of the change value exceeds the threshold for negative change value decision. A fire deciding means outputs a fire signal when the dimming rate is higher than the threshold for fire decision over a prescribed number of times of sampling. Thus, probability of failure in reporting of even a slowly raising fire is reduced and the fire is surely decided.

Title: Gas sensor
Inventor: KANBARA TERUHISA
IPC: G01N27/12
Filed: 1984-10-19
Abstract: PURPOSE:To achieve a greater sensor sensitivity, by replacing a part of Me (Me: Zr or Hf) in a substrate material SrMeO3 with Al. CONSTITUTION:As the oxygen partial pressure lowers, O in the Me-O-Me bond of a crystal is released out of the crystal as separation and the resistance increases in proportion to the release thereof. For example, O in the Zr-O-Al bond is easier to separate than the Zr-O-Zr, resulting in a greater deal of separation at the same oxygen partial pressure. Thus, a greater sensor sensitivity can be achieved by replacing a part of a substrate material SrMeO3Me with Al.

Title: Method and device for producing plasma and method and device for plasma processing incorporating them
Inventor: WATANABE KATSUYA
IPC: G01N24/14
Filed: 1994-09-14
Abstract: PURPOSE:To produce high-density uniform plasma which uses microwaves, by producing plasma in a discharge space having the same diameter as a cavity part, and allowing a specific mode microwave to go in resonance between the microwave reflecting boundary surface of the plasma and the cavity part reflecting end face, CONSTITUTION:Microwaves generated with oscillation of a magnetron 61 are fed to a cylindrical cavity part 64 via a rectangular waveguide tube 62 and a cycle/rectangle converting waveguide tube 63. When the distance from the top plate 641 of the cavity part 64 to the plasma boundary surface 151 is integer times as large as the half of the intra-tube wavelength in a certain mode, resonance occurs, and a standing wave exists between the top plate 641 and the plasma boundary surface 151. A microwave introduced anew to the part 64 from the tube 63 is superposed on this standing wave, and the microwave in a mode having the same intra-tube wavelength of the standing wave makes resonance with the standing wave so that an intense electric field standing wave is generated. Modes which do not meet this condition will attenuate and are not allowed to exist between the top plate 641 and the surface 151. If the height of the part 64 is selected properly, therefore, the microwaves of intense electric field can be led to a vacuum vessel 67 via a microwave transmission window 66 and shower plate 611 while the mode in the part 64 is held as it is.
